NOTTS.—For experiments Nos. 1, 15, 25, 35, 46 and 60, the jacket was loose.
During tho above oxporimontH, tho weight of the dynamometer, and of that portion of
the shaft which was above tho lowest coupling was 1,300 Ib.
With tho flume empty, a strain of 1.0 Ib., applied at a distance of 2.4 ft. from the center
of tho shaft, sufficed to start tho wheel.
